Fairly straight forward script that I was sure to fix to my best ability:
Code:
[ENABLE]
{$lua}
--For negative integers, in lua,I used 4294967296-(value) in the calculations (4 bytes)
setGlobalKeyPollInterval(10)
setGlobalDelayBetweenHotkeyActivation(10)

if hk
   then hk.destroy()
end

local hk = createHotkey(function()

      player_xMouse = readFloat("[engine.dll+495468]")
      player_yMouse = readFloat("[engine.dll+495464]")
      player_xPos = readFloat("engine.CreateInterface+1AF8A8")
      player_yPos = readFloat("engine.CreateInterface+1AF8B0")
      player_zPos = readFloat("engine.CreateInterface+1AF8AC")
      rocket_xPos = readFloat("engine.CreateInterface+19D298")
      rocket_yPos = readFloat("engine.CreateInterface+19D2A0")
      rocket_zPos = readFloat("engine.CreateInterface+19D29C")

      Get3dDistance = math.sqrt(((player_xPos - rocket_xPos) * (player_xPos - rocket_xPos)) + ((player_yPos - rocket_yPos) * (player_yPos - rocket_yPos)) + ((player_zPos - rocket_zPos) * (player_zPos - rocket_zPos)))

      --Use the well known 3d distance formula to see how far 2 players are from each other
      --Almost every 3D game uses this formula. 2D games use a simpler variation
      function AimAtRocket(r_xPos, p_xPos, r_yPos, p_yPos, r_zPos, p_zPos, p_xMouse, p_yMouse)

               pitchX = math.asin((r_zPos - p_zPos) / Get3dDistance) * 180 / math.pi

               yawY = -(math.atan2(r_xPos - p_xPos, r_yPos - p_yPos) / math.pi * 180 + 180)

               --Set our  mouse values with our new YAW and PITCH
               print("yawY: " .. yawY .. " pitchX: " .. pitchX)
               writeFloat(p_xMouse, yawY) --Actually does nothing, however manually changing them produces correct effect
               writeFloat(p_yMouse, pitchX) --Actually does nothing, however manually changing them produces correct effect
      end

      AimAtRocket(rocket_xPos, player_xPos, rocket_yPos, player_yPos, rocket_zPos, player_zPos, player_xMouse, player_yMouse)

end, VK_SHIFT) --End of Hotkey Function, and assign d to activate the function.

-- If you don't want to affect all other hotkeys, just change this hotkey:
hk.DelayBetweenActivate = 1

{$asm}
//Start of Assembly Script
[DISABLE]
//End of  Assembly Script

Now, the unsolvable part is in the AimAtRocket function, which is supposed to set my player's aim to the desired aim, however, it does not, even though I can print the yawY and pitchX as correct Floats. I tried putting those lines outside the function, or replacing p_xMouse and p_yMouse with their corresponding actual address (replaced it with the origion xMouse), but to no avail.

Code:
writeFloat(p_xMouse, yawY) --Actually does nothing, however manually changing them produces correct effect

Ok, what p_xMouse is? Looks like this variable doesn't hold an address.

It's a parameter in the function, the parameter should be replaced by what is put in
Code:
AimAtTarget(parameter1,parameter2,parameter3,etc)

Look at your code again.
Code:
-- player_xMouse is a float
player_xMouse = readFloat("[engine.dll+495468]")

-- player_xMouse passed as 7th parameter to function AimAtRocket
AimAtRocket(rocket_xPos, player_xPos, rocket_yPos, player_yPos, rocket_zPos, player_zPos, player_xMouse, player_yMouse)

-- 7th parameter is named p_xMouse
function AimAtRocket(r_xPos, p_xPos, r_yPos, p_yPos, r_zPos, p_zPos, p_xMouse, p_yMouse)

-- p_xMouse actually contains a float, not a pointer, so this fails
writeFloat(p_xMouse, yawY)

I don't understand what you mean, both p_xMouse and player_xMouse are floats, same with every other variable assigned like player_xMouse, so why would p_xMouse need to be a pointer if yawY is also a float? Unless writeFloat requires an address not a number.

I take it you just copied and pasted that code from somewhere else without knowing what it does.

This documentation in celua.txt might help you:
Code:
writeFloat(address,value) : Writes a single precision floating point to the specified address.

Changed:
Code:
player_xMouse = "engine.dll+xxxx"
and now it works.
